FLOAT-VALVE MECHANISM FOR CRBURETERS.

Specification ofvLetters Patent.

Patented Feb. 22, 1916.

Application med-November 5, 1914. Serial No. 870,364.

To all whom t may concern:

Be it known that l, SEBASTIAN G. BEINK- mix, a citizen of the United States, and a resident of Fords, in the county of Middlesex and State of New Jersey, have invented certain new and useful Improvements in Float-Valve lvlechanism for Carbureters, of.

which the following is a specification.

T his invention relates to a float valve mechanism for carbureters, by which the inflow of the gasolene into the liquid fuel chamber is regulated.

rhe invention comprises more particularly .novel and eflicient means for maintaining the float always at right angles to its axis of movement so that any jamming of the valve and its operating parts is effectively prevented. Y

ln the accompanying drawing: Figure 1 is a vertical central section of a float valve mechanism embodying my invention, showing the same applied to a carbureter; Fig. 2

a cross section on line 2 2 Fig. 1, and Fig;

3 a perspective view of the valve-actuating rfork.

Around the shell 1 of a carbureter of'suitable construction, is fitted an annular liquid.

fuel chamber 2, shown to consist of'a head 3, a base il, and a roundV transparent side 5. From base 4e there extends upwardly, a pair of posts or bearings 6, in which4 is journaled by pin 7, a fork A, which is more fully shown in Fig. 3. rl`his fork is composed of a web 8, a pair of Shanks 9 extending inwardly therefrom, and a pair of parallel lugs 10, extending outwardly therefrom. lli/Teb S is located between bearings 6, and is apertured as at l1, for the accommodation of pin 7. Shanks 9, diverge from each other and are movably secured to the lower side of an annular' float l2 which is vertically slidable along that portion of carbureter shell 1, which extends axially through chambei' 2. The movable connection between shanks 9 and float 12 is eifected by a pair of Vseated on a nipple 16, through which the liquid ,fuel is admitted to chamber 2. It will be seen that asL float 12 falls, lugs 10,

will lift the valve, while when the lloat rises, the lugs will close the valve, so that in this way the supply ofthe fuel is regulated by the position of the float, which is in turn controlled'by the quantity of gasolene supplied` by chamber 2 to thecarbureter. q

'. In order to steadythe Am vement of the valve operating means described, there is installed a second fork Bwhich is mounted .Y

with its'axis at right angles to that offork A and consequently crosses the latter. ThisV second fork is composed of a web 17 and a pair of diverging Shanks 18 extending inwardly therefrom; Web 1-7 is by pin 19 piv-` oted toa pair of posts 20, extendingV upwardly from base 4, and located' at right angles to posts 6. secured to the lower face of float l2 by staples or keepers 2l, which loosely encompass the Shanks and arearranged intermediate staples 13. Itwill be seen that by the con struction described, each of the forks engages the float at diametrically opposite points, while the points engaged by oneV of the forks are located midway between the points engaged bythe other fork.V As the comparatively long bearing pins 7 and 19 respectively of the forks A and B preclude any lateral dipping of said forks, it is evie dent that owing to the peculiar overlapping thereof the annular float is bound to always occupy a position ythat extends in parallelism with the top andbottom of chamber 2. ln other words, the float 12 although absolutely free to follow thergeneral fall and rise of thev liquid level, within chamber 2can- 'not participate in any deflections of the liquid surface out of the horizontal, due to shocks, sudden changes in speer, varying inclinations of the car, etc., butsaid float Shanks 18, are slidably' will invariably occupy aV position extending l l at right angles to the axis of chamber 2, so that any undesirable 4vibratory movements and a jamming between the float, its Vguiding means and the fuel inlet valve is effectively prevented.

I claim: y f p 1. A float valve mechanism for carbureters comprising a fuel chamber, an inclosed float, a pair of independent forks each of which engages the float, and a. valve 'operatively connectedV to one of the forks.A

2. A iioat valve mechanism for carbureters comprising a fuelV chamber, an inclosed float, a pair of independent forks set at right angles to each other7 one of said forks engaging the float at points loe-ated midway between the points of engagement of the other fork with the float, and a Valve operatively connected torone of said forks.

3. A iloat valve mechanism for carbureters, comprising a fuel chamber, a pairy of pivoted forks, set at right angles to each other and oseillable on horizontal aXes only, a boat directly engaged by each of the forks at points located midway between each other, lugs extending from one of said forks, and a valve oineratively engaged by said lugs.

4. A float valve mechanism for carbureters, comprising a. fuel chamber, an nolosed float, a plurality of members that are oscillable on a horizontal axis only and are each adapted to directly engage the loat at different points, and a Valve operatively connected to the float.

A float valve mechanism for carbureters, comprising a fuel chamber, an inclosee float, a plurality of fixed bearings arranged sidewise of each other, a plurality of members oivoted to said bearings and oscillable on a horizontal axis only, means for movably Connecting said members to the float, a valve, and means on one of said members for actuating the valve.
